[Vertigo in patients with otosclerosis and post stapedectomy].

The aim of the paper was evaluation of behaviour of the balance system in patients with clinical otospongiosis and after stapedectomy. The investigation was carried out in 131 otosclerotic patients. Before and post operation vertigo was noticed and the spontaneous nystagmus, positional nystagmus and directional preponderance in kinetic test were examined in ENG. Vertigo and objective symptoms of disturbance of the vestibular function were found in clinical otospongiosis, but postoperative subjective and objective symptoms were more frequently.
